CMMR series

45° first surface mirrors

Production environments often present size constraints, limiting the choice of optics and sometimes sacrificing optical performance for size compatibility. CMMR series is the Opto Engineering answer, producing a 90° bend in the light path and opening new installation options for your application.

CMMR series is a family of first surface mirrors designed for our telecentric lenses and illuminators which enables viewing at 90° to the optical axis of your telecentric lens and camera.
These right-angle mirrors can also be used together with collimated illuminators, reflecting incident rays coming from the light source at 90° angle.

CMMR series feature a precise tightening knob that allows for easy and secure clamping. In addition, compatible protective windows are available. Whenever overall system dimension and precision alignment are critical factors for your application, CMMR series is the ideal choice.

Additional clamping mechanics are required to adequately support combination of CMMR with telecentric lenses and illuminators. CMHO series clamping mechanics can be used prior to verification of mechanical compatibility (see CMHO series mechanical drawings available online). CMHO is not compatible with the combination of the following two products: CMMR and TC13xxx.

CMMR4K models

CMMR4K are 45° first surface mirrors that produce a right angle bend in the light path.
CMMR4K are available in two versions: -V and –L, respectively bending the light rays vertically (either upwards or downwards) or laterally (either to the left or the right).

Additionally, length of CMMR4K mirrors can be varied to precisely adjust the distance of the mirror from the front lens of TC4K/LTCL4K. Refer to the schematics for further details.
